Asking for a friend. Can't think where to post this. Here is their included text: "Interesting from Chris Hardy- There was a 4 door small sedan. Maybe white or silver driving around attaching a weird small device to fences. I noticed it on a neighbors and the new construction property. We called the police and they took it as evidence. Did it to many other homes on as well. Attached to the bottom of a the fence. Looks like two bottle caps fused together w a paper thing inside. Very odd."
